The show spans Rush’s three-decade career, from his landscapes in Vermont and Massachusetts to his cityscapes in Venice and Brooklyn. It’s called, aptly, “Places.”

“Location has always meant a lot to me,” said Rush, who, ironically, is very much a “lifer,” living in Brooklyn for 40 years and teaching art at Packer Collegiate Institute in Brooklyn Heights for 33.

Of the 30 pieces hanging among the peonies, orchids, tulips and roses are his Vermont cottage houses, Massachusetts fields, and moody recalls of the canals in Venice. There’s also on-site portraits of the Gowanus Canal, which is “like a Venetian canal, albeit very polluted,” said Rush, who used to paint by the edges of the canal in the 1970s.

“Places” by Ken Rush at Opalia Flowers [377 Atlantic Ave. between Hoyt and Bond streets in Boerum Hill, (718) 643-9160], May 12-June 10, with an opening night reception from 6 to 8 pm.
